DETONATIONS IN HYDROGEN SULPHIDE-AIR CLOUDS

The paper reports on an investigation to determine the detonation hazards of hydrogen sulphide/air mixtures in relation to the detonation hazards of other more common fuel-air mixtures. Parameters which characterize the sensitivity of fuel-air mixtures to detonation are discussed. Theoretical and empirical realtions between the various detonation parameters are also described, and the current status of detonation hazard evaluation is summarized. Finally, the results from a series of hydrogen sulphide/air field trials are used together with previous results and numerical calculations to determine the sensitivity of this mixture to detonation. It is found that hydrogen sulphide forms a mixture with air that is less sensitive to detonation than most common gaseous hydrocarbon fuels except methane.
